MIDI: At long last, though quick and dirty, pitch bend depth! Or, I think it works. Tested on two
...
files. Let me know if anyone discovers any problems with this. This commit also includes Nils's synth
loop optimization patch. I hope committing it does not cause problems.

Increase output buffer size to 32kB, results in less buffer missing in general and avoids buffer misses when lcd remote is plugged in while playing and ticking reduction is enabled. Increase max voices used on coldfire targets to 24 and reduce voices used on pp targets to 16. Put one more struct in iram for a slight speedup on coldfire. Fix comments in midiutil.h

Optimisation of the midi player, reducing the number of multiplications and memory accesses inside a very frequently executed loop, also does shifting of the whole sample when synthing is done which improves accurracy slightly, ~10% fewer buffer misses

static/inline/iram raid gives nice speedup

Maybe 25 was too much with the new decay rates.

MIDI: Kick up number of voices and decrease the decay rate, taking
...
advantage of the recent speedups. Some instruments sound a lot more
natural now.

Do not duplicate const table, make getEvent function static inline, gives about a ~1.5% speedup, put tick function in iram, ~3.5% speedup

Simplify the sendEvent function, makes it _slightly_ faster and quite a bit smaller, build midiplay with -O2 for coldfire, gives about a 23% speedup

Move all of midiplay into its subdir and add a Makefile for it, add header files as necessary.
